Can lsd kill brain cells?
No, LSD is very non-toxic compared to most recreational drugs. It does not cause any physical damage to the body or the brain. All risks associated with LSD are psychological risks, it can be dangerous, but it wont cause physical damage unless thousands of doses are consumed at once. But I must stress that the psychological dangers are very real, and not fully understood yet, and that LSD should be no means be regarded as “safe”.
